[Mylloon]

I share a folder between my Obsidian vault and the folder PineDocs uses with Syncthing (because the machine that runs PineDocs is not my laptop), so as soon as I save my files the site is immediately updated, but PineDocs was not designed with Obsidian in mind, the links work but not the advanced features Obsidian offers.

On the other hand, Perlite [1] is (I never really tested it but it looks cool) designed with Obsidian in mind so maybe it supports more features.
